I have the same issue. My name starts with K and I can’t tell you how much I DREAD introducing myself, especially in a meeting/large group. Like the comment above, I usually try to say a very long sentence (which probably sounds weird and overly formally to anyone listening to me) and then try to slide into my name at the very end. Sometimes my brain lets me get away with; sometimes it doesn’t. I work from home so if I think about to block, I pound my thigh to try to break it. It’s not great but I can usually get it to break after a few tries. I don’t order from my partner at the drive thru because he always wants a “double” something so I get it with the Ds! Honestly, I’m getting to the point in my life now in my late 40s after having dealt with this since I was 5yo where I just don’t care anymore. If I stutter over something, it’s not the end of the world. I’ll recover and anyone I care about will care enough me to not care at all.
